Considered in its more specific aspects, another object of thisinvention is to improve upon the means forautomatically'a'nd'progressively varying the distance of the cuttingknives from ated: if I. v i

For the accomplishment of. these and such furtherlobjects aswill'hereinafter be apparent to those skilled in the art to which this'appertains, the invention consists intheconstruction, combination andarrangement of parts herein specifically described and illus trated intheaccompanying drawings, wherethe head as the clipper is actu in isshownapreferred embodiment of the invention, but it is to be under'stoodf that claimshereunto appended. g i "In the drawings forming a portionof this specification; 4 v '5 Fig. 1 isa section on the line-1'1.ofFig.2.

As shown inthe' drawings, a base plate 10 has extending upwardlytherefrom, a yoke 11, the arms 12oflwhich actas guides forengagementby.thenotches13 cut into the sides of the lower .cutting knife .15. s The1 lower 1 Fig. 5is a section on the line,5 5 ofFig.

A tongue 23 projects radially from the boss 20 of the handle 21 and isbent downwardly to engage a slot 24 in the upper cutting knife 25' whichis dovetailed as ,at 26 toa similar knife 27. Theknives 15, 25 and 27amprovided' with comb-like cutting teeth; in the usual manner ofdevicesofthis character. A torsion spring 28 is coiled around :thepin 22and has one of its ends anchored to the :block17 and its other end incontact with the tongue 23 to no rmally I away from the handle 29.

changes, variations and modifications maybe resortedto'which fall withinthe scope of the urge the handle 21 Slidably-m'ounted in a smallboss 30fixed wheel '33." The ratchet wheel 33 is fixed upon the lower end: ofaiscrew' 34Land is rotatably received in arsocket 35 in theupper end ofthe block 17. A screw cap 86 is threaded onto :the' threaded reducedupper end of the segmental bushing 9 and engages. against the upperfaceof a cup-shaped housing 37 and ';clamps the housing against theshoulder 38 :of theibushing 9. v The handle 291s preferably integralwith i the housing 37 and the parts are so'proportioned that when thehousing is engaged by .the cap. screw 36, its lower; face will contactwith the knives'25 and 27 to hold them neatly :in-v sliding engagementwith the lower knife placement;- Thefcentral portion of each of f Theknives 25 and 27 are provided with the slots 38 in which'the lugs 39projecting up- :wardly from the lower 1 knife 15 engage to hold theupper knives against horizontal dis as at 41 to provide suflicientclearance to permit the knives to reciprocate.

Slidably mounted on the yoke 11 are the members 42 of a split nut,having the aperhires-4C3 therein to receivethe inner ends of members.4:4-w11ic11 are secured to. the handles 45. The latter are slidablymounted in the elongated slots 46, springs 47 being provided tonormally-hold the halves of-the -nutin enga ement with the threads ofthe screw-.

bruiding means are provided to be attached to the users head when it isdesiredto use the device and said means comprises .the spring clamps '50adapted to be engaged over 15 the top of the head and the neck of theuser.

These. clamps comprise upper and. lower spaced membershl and 52 between.which the ends 53 of the verticalguide 54- are'slidably receivedTheup-per member 52' is provided so .withaa-slotoo having alplurality ofspaced notches 56 therein which notches are adapted to be engaged by theheaded pin 57'. The guide 54; is provided along one edge with theupwardly extending flange 58 against which the side of the clirperlisaplaced when in use.

The. operation of the device is as follows: the handles: 45 arep-ressedinwardly to release the splitvnut 42 and thescrew carrying thek.nives15,:.-25and 27 with it is moved so downwardly until theknives-contact-with the baseplate 10. If it isdesired to cut'thehair onthe back of the head, the cut is preferably started at the neck anda'sthe handle 21-is operated, the: pawl 31 will cause the screw 34 to beautomatically actuated to gradually move! the. knives away from thebase; plate therebyvaryingthedepth of the'cut in a manner which will beobvious.- If desired the-cut could'be started at the top and workeddown- 40 wardly, the, knives being raisedtofthe desired height andi thepawl 3l.turned in the direction to cause the knives to move downwardly..To insure thatthe whole surface of=the backportionz of the head'may becut, the guides'shown in. Fig; .6 aroused, the clips are placedover'thetop of the head and the neck respectively. and the ed eofitheclipper is:hcld against the'flange 58 ofithe guide 54,whilemakingacut.
